This is used to compute the current state of a contact manifold.
public var m_normal:b2Vec2
world vector pointing from A to B
public var m_points:Vector
world contact point (point of intersection)
public function b2WorldManifold()
public function Initialize(manifold:b2Manifold, xfA:b2Transform, radiusA:Number, xfB:b2Transform, radiusB:Number):void
Evaluate the manifold with supplied transforms. This assumes
modest motion from the original state. This does not change the
point count, impulses, etc. The radii must come from the shapes
that generated the manifold.
Parameters
